I am developing a MATLAB GUI using app designer. I want to create a button which deletes specific variables. The variables are initially set using the setappdata function.

Hard, or impossible, to say without seeing your code.

I've only really used appdesigner once, but apart from its annoying way of not allowing you to edit parts of the code it creates it is just based on a class whose entire purpose is to share data between its functions.
Show the code that you have, as Image Analyst says, to enable people to be more help.

It depends on what "delete" means.
You do not create variables by the setappdata command, but this function stores the contents of the variables in the ApplicationData of a GUI element. Afterwards you can remove the entry by rmappdata, as mentioned in the documentation of setappdata.
